Nothing can soothe your soul than staring at the bright little stars that rest in the dark sky. Do you think it looks the same way it does to us? Not at all. Stars are always a mystery! This article focuses on the unknown facts about stars. Read along to know more about the age of stars, average size of a star, and star characteristics.
Stars are spheres in nature and are made up of plasma. Yes, the shape we think of a star is completely different from its real shape. A slow rotating cloud that is almost made of helium and hydrogen collapses inward and shrinks due to the gravitational pull with quick spin turns into a rough sphere.
Below listed are the methods handled by scientists to calculate the age of stars.
The stars in a cluster are thought to have formed from the same cloud of gas and dust, giving them a similar age. Scientists can determine the cluster’s age and, consequently, the age of its stars, by examining the features of the cluster and its stars.
The age of a star can be calculated from the known rates of decay of several radioactive isotopes found in stars. One method to determine the age of a star is to look at the ratio of specific uranium and thorium isotopes.
This technique includes examining the oscillations, or “starquakes,” that some kinds of stars experience. The frequency and pattern of these oscillations can be analyzed to determine the star’s age.
